The framed letter sits atop a concrete NYPD barrier, amid flowers and toys honoring Alyssa Elsman of Portage, Michigan, who was killed when 26-year-old driver Richard Rojas zipped down the sidewalk for several blocks last Thursday.

In the letter, Elsman's father describes his grief and heartache, and expresses gratitude to those who have supported the family.

"I have met so many people from different countries, religions, creeds, etc... you have shown us that when you remove bias, racism and ignorance, WE ARE ALL ONE," he writes. "Your condolences have been sincere and taken to heart."

Part of the letter also describes how Elsman loved New York City: "She loved Times Square. She would appreciate all your kind words but would also tell you all to get back up and continue, that's how full of life my daughter was."

The letter ends, "I have a hole in my heart... I love you kid... Love you, love you, love you."

Kim Spears, who works nearby, had tears in her eyes after reading the letter.

Elsman's 13-year-old sister Ava was also critically injured in the accident and had been at Bellevue Hospital with a broken pelvis and a collapsed lung.

Six other victims continue to be treated at Bellevue, one of whom remains in critical condition, a hospital spokeswoman says.

Rojas was taken into custody after barreling into the lunch-hour crowd on Seventh Avenue shortly before noon Thursday, according to police. Officials and sources say Rojas, who has a history of DWI arrests, made a U-turn on Seventh Avenue at 42nd Street and started speeding down the sidewalk for about 3-and-a-half blocks, mowing down pedestrians before crashing into a traffic pole.

One of the other victims has been identified as a New Jersey high school student.

Jessica Williams, a 19-year-old student from Dunellen High School, remains in critical condition, according to a GoFundMe page dedicated to her recovery. She was visiting midtown on Senior Skip Day with a friend when Rojas accelerated and slammed into them and the crowd.
